In PV modules, many different components are exposed to the sunlight. Therefore, the IEC 61215 defines a UV preconditioning test (MQT 10) to test whether these components can withstand the UV radiation of the sun.

In our test chamber, the UV radiation is up to five times the sun intensity to accelerate the test, as requested in the UV preconditioning test.

During the test, the module temperature is kept constant at 60°C in a special temperature chamber. We deliver our UV preconditioning chamber turnkey including the data acquisition unit, radiation and temperature sensors.

For waste heat disposal, the chamber is equipped with a water/air heat exchanger that can be connected to a cold water grid. This minimizes the heat load in the room were the chamber is installed.
